Eto'o Toure Schweinsteiger were neither lazy nor bad professionals. Deco and Ronaldinho probably were.
I also think you can't underestimate the age of our fullbacks. It's unlikely all four will stay.
Schweinsteiger was not Guardiola's idea, that was Bayern allowing him to play in a different league (Something he wanted to do) while he still could.
Eto'o was binned because his response to Guardiola telling him how to play was reminding Guardiola he'd never been a great player and had done nothing as a coach. Awful attitude, poor professional.
Yaya wasn't a fan favourite.
Zabaleta is our best RB, the type of fullback Pep likes, is 2 years younger than Sagna and a great presence in the dressing room and leader on the pitch.
If he leaves it won't be because Pep forced him.
